a crashcourse on the knees

Summary:

"If.. gege wishes to practice on me, then this San Lang would be honoured to allow him,” he murmured, stroking the back of Xie Lian’s hand with his thumb.
Xie Lian looked at him for a moment, then beamed at Hua Cheng.
"Thank you, San Lang! Although, I just realised...” Xie Lian lowered his voice and frowned a little, "do you think you’re able to get hard? I guess that would be the most optimal when training."
"No worries, gege,” Hua Chang said dazedly, "you do not have to think about that."

Xie Lian has never sucked a dick before. Luckily, he has someone who is willing to help him practice.

Notes:

Happy new years! What could possibly be a better way to start 2022 than by posting my first Hualian fic? 💫

Work Text:

"San Lang,” Xie Lian murmured with his eyes glued to the screen in front of them, "I was wondering about something."

Hua Chang, sitting next to him whilst scrolling on his phone, looked up and turned his attention towards Xie Lian.

"What’s on your mind, gege?" he inquired curiously.

One of his arms was resting on top of the coach behind Xie Lian, and his fingers were tapping the coarse material as he waited.

Xie Lian felt his cheeks heat up but didn’t look away from the TV.

They had been lounging at home together as always, Xie Lian watching a random TV show while Hua Cheng was content just hanging out and tapping on his phone.

The flat they shared was in perfect walking distance to the university they both attended, and after they had met during their first year, they’d been nearly inseparable. It was Hua Cheng who had found the apartment, and Xie Lian had been overjoyed to be able to leave his prior chaotic student housing behind when Hua Cheng offered the second bedroom to him. Although the flat was small it fit the both of them perfectly, and the fact that they had no issue living a bit on top of each other was also helpful. They kind of preferred it that way, anyways, finding the company enjoyable and comforting.

Usually, Xie Lian had no problem speaking his mind to Hua Cheng, whatever the topic might be. There was pretty much nothing that they hadn’t discussed before, anyway, except for one thing.

Sex.

Although Xie Lian thought that Hua Cheng was the most handsome person he had ever seen, his slightly teasing smile always so warm and open towards him, he’d never heard the man talking about meeting up with other people. Neither was there ever a Friday or Saturday night that Hua Cheng didn’t spend with him, so it didn’t seem like he tried to find someone to hook up with, either.

He still seemed so confident, though, so self-assured and coolheaded, that Xie Lian found it quite impossible to imagine the man as a virgin, or as someone with zero experience, like himself.

The most action Xie Lian had ever experienced was an innocent kiss with a girl at a birthday party when he was 9, before he was pulled away by a yelling Feng Xin, warning him about the dangers of girl lice.

That was the most intimate Xie Lian had ever been with a girl — when he turned 17, he realised that his gaze was floating towards guys instead, and that he held more attraction towards men than women. That said, he had never met a guy he really liked, not until he met Hua Cheng and they grew close. Hua Cheng was always so kind and understanding, yet funny and charming, and Xie Lian couldn’t quite believe that he’d lucked out getting a friend like that, considering his notoriously bad luck. 

All in all, Xie Lian therefore had a terribly poor understanding of sex. He understood the basics, with what went where and how, but having no hands-on experience, he didn’t really get it.

On the TV show he was watching, the girl had just kneeled in front of the male character, and the latter was moaning loud and clear as she was doing something the cameras weren’t showing.

Xie Lian coughed.

"Gege?" Hua Cheng let his fingers wander to the back of Xie Lian’s head, lightly pulling at the bun fastened there to get his attention.

"Ah, San Lang,” Xie Lian’s gaze flickered down and he rubbed his chin sheepishly, "I’m not really sure how to talk about it."

He could feel the warmth of Hua Cheng’s stare on his face and coughed again, avoiding eye contact.

“Gege," he could almost hear the pout in Hua Cheng’s voice, "you know you can talk to me about anything."

He slid a little closer to Xie Lian, tilting his head. "What is it?"

Xie Lian chewed on his lower lip for a second, then turned earnest eyes towards Hua Cheng.

"Promise you’ll not laugh at me?"

Hua Cheng shot him an easy smile.

"I promise."

“Okay.” Xie Lian took a deep breath and looked down at his hands again, "I’m just... I’ve never... Ah, San Lang... It’s so embarrassing!"

Hua Cheng’s long, slender fingers moved into his vision as he grabbed one of Xie Lian’s hands.

"Nothing you could ever say would be embarrassing to me,” Hua Cheng appeased. ”Believe me, gege."

Xie Lian hummed hesitantly, then sighed.

"San Lang, I was just wondering... Have you ever... Ah, gone down on someone?"

He felt his cheeks burning and firmly held his stare on their hands.

Hua Cheng was quiet for a moment, making Xie Lian nervous. What if he had crossed the only line that existed between them?

He opened his mouth, prepared to apologise and take it back, when Hua Cheng answered.

“I... Why does gege ask?" his tone had changed, a little lower now, more intense.

"The show...” Xie Lian gestured towards the TV and Hua Cheng followed the motion, then chuckled deeply.

The couple on-screen had now moved over to a bed, where it this time was the man that used his mouth to pleasure the other.

"Ah, I see what roused gege’s curiosity,” Hua Cheng murmured. “You’re thinking about oral sex?"

Xie Lian nodded silently, cheeks aflame.

“Hmm.” Hua Cheng was silent for a second. “Is it a woman you want to satisfy?"

This time, Xie Lian shook his head, still not meeting Hua Cheng’s stare.

Somehow, they had never talked about their sexualities. Xie Lian knew that Hua Cheng would probably accept him, considering his supportive and kind personality, but waiting for his reaction made him queasy.

After another moment of quietness, Hua Cheng took a heavy breath.

"You want to talk about going down on a man?" he asked, voice unnervingly passive.

Xie Lian look up with panic and noticed how stiff Hua Cheng had turned, then started waving his hands.

"Ah, never mind, never mind, San Lang,” he laughed awkwardly, "it was just a stupid thought. Please don’t mind me."

Hua Cheng, gaze still heavy, grabbed one of his flailing hands and held it still.

"You’re misunderstanding me, gege,” he drawled, suddenly relaxing again. ”I just wanted to understand what you wish to talk about. There isn’t anything I wouldn’t discuss with you."

"Ah, San Lang,” Xie Lian rubbed his nose, "you’re very patient with me."

"Not at all,” Hua Cheng murmured. “What would gege like to know about sucking cock?"

Xie Lian’s eyes widened at the crude wording.

"Oh, only... Ah, you see, I’ve never done it myself... So I don’t know anything about it,” he stuttered, eyes focusing on his thighs and how close they were to Hua Cheng’s slightly bigger and stronger ones.

Hua Cheng took another deep breath.

"Ah, gege has no experience with it?" A second passed, before he added, "not with receiving, either?"

Xie Lian shook his head, unsure why Hua Cheng suddenly exhaled heavily.

"I’ll help gege understand how one does it,” Hua Cheng murmured, voice slightly more strained.

Taking a risk, Xie Lian lifted his gaze again and looked at the other man.

Hua Cheng’s mouth was somewhat open as he gazed back at Xie Lian, his eye intense and attentive.

“I... I understand how it works, in theory,” Xie Lian said, turning himself towards Hua Cheng a bit. “... It’s the actual execution I don’t get."

Hua Cheng didn’t answer, continuing to listen attentively to Xie Lian’s every word.

"Ah, San Lang,” Xie Lian mumbled, "is your gege horribly ill-mannered if he asked...”

"If he asked what,” Hua Cheng rasped immediately.

Xie Lian swallowed.

"If he asked if he could practice on his dear San Lang?"

Hua Cheng stared at him, eye wide in disbelief. Xie Lian rubbed his chin again.

"Ah, if it helps, it would only be so I could feel what it’s like,” Xie Lian hurriedly explained, "it doesn’t need to mean anything. It’s just that there is no one that I trust or feel more comfortable with than my San Lang. But, if you want to, I could ask someone else inst–“

“No,” Hua Cheng interrupted him, "there is absolutely no need for that. Gege, please never ask anyone else for something like this. Promise me."

Surprised at the harsh tone, Xie Lian hurriedly nodded in agreement.

Hua Cheng dragged a hand over his face, his expression still incredulous, then used it to grab Xie Lian’s hand.

He made direct eye contact with the latter, looking between one eye to the other, scrutinising him.

"If.. gege wishes to practice on me, then this San Lang would be honoured to allow him,” he murmured, stroking the back of Xie Lian’s hand with his thumb.

Xie Lian looked at him for a moment, then beamed at Hua Cheng.

"Thank you, San Lang! Although, I just realised...” Xie Lian lowered his voice and frowned a little, "do you think you’re able to get hard? I guess that would be the most optimal when training."

"No worries, gege,” Hua Chang said dazedly, "you do not have to think about that."

Xie Lian was a little confused, but smiled and nodded before he slid to his knees in front of Hua Cheng.

The latter took a new, deep inhale and watched intently as Xie Lian rested his hands on Hua Cheng’s muscular thighs. The man was wearing dark jeans with a few cuts and rips, which made Xie Lian graze a little bit of skin as he moved his hands up and down a few times.

With joyful glee, Xie Lian noticed that Hua Cheng’s length already was slightly tenting his pants, the thick size of it visible against his right thigh.

Xie Lian knew that he could count on his San Lang!

"How should I start?" he inquired, looking up at Hua Cheng’s face.

Hua Cheng blinked a couple of times, awakened from his heavy stare on Xie Lian, then shot the man a small, teasing smile.

"Depends on what you want, gege,” he responded. "This is your chance to practice, after all."

Xie Lian pouted.

"You’re to no help, San Lang,” he complained and sighed, "I just want to make this enjoyable for you."

"Again, there’s no need to worry about that, gege,” Hua Cheng exhaled, gaze flickering towards where Xie Lian’s hand was inching closer to his dick, "I’m already enjoying myself tremendously."

Xie Lian’s lips curved into a self-satisfied smile.

"That’s good,” he said. "Please let me know if I do anything wrong, okay?"

Hua Cheng nodded, leaning back against the couch as he observed Xie Lian’s actions.

Xie Lian kept rubbing Hua Cheng’s thighs for a little while, then sat up properly before he slid one hand to the outline of the dick.

Hua Cheng inhaled sharply as Xie Lian gently palmed the stone-hard length, softly rubbing the head before stroking down the shaft.

Hua Cheng’s hips bucked as Xie Lian repeated the motion, making Xie Lian use his available hand to hold them down.

"Is this good?" he inquired softly, throwing a glance up at Hua Cheng.

The latter’s cheeks had turned somewhat peachy, and he immediately nodded affirmatively.

"Please continue, gege,” Hua Cheng breathed, hips still slightly stuttering at the slow movements.

Xie Lian hummed, then kept stroking the outline, memorising the places where Hua Cheng let out low gasps or deeper groans. After a while, he moved his left hand to Hua Cheng’s belt.

"Can I open your jeans, San Lang?"

"Please."

Biting his lip, Xie Lian unbuckled Hua Cheng’s belt, then made quick work of his button and zipper.

His erection was already pushing to escape the boundaries of the skinny pair of jeans, the shape easy to recognise beneath Hua Cheng’s crimson red boxers. It had already leaked quite a bit, making some of the textile darker than the rest, but Hua Cheng didn’t seem to mind at all.

Carefully, Xie Lian grasped the clothed dick to help it out of the jeans, gasping as the touch made Hua Cheng groan. The cock was even warmer when he felt it through only a layer of fabric, and it was twitching in his hold as he inspected it.

"You’re so hard, San Lang,” Xie Lian pointed out.

"I truly am,” Hua Cheng murmured, "fuck."

It wasn’t often Xie Lian heard Hua Cheng swear, so it really emphasised how affected he was.

He wasn’t the only one, though — Xie Lian could feel his own length strain against his pants, and arousal was thrumming through his veins.

Xie Lian licked his lips as he stroked Hua Cheng one last time through his underwear, before lifting the material away from the thing tenting it.

He gasped.

Hua Cheng was huge.

Immediately as it was released, the dick bounced back against Hua Cheng’s abdomen, curving slightly to the right. It was long and thick, with visible veins on the underside and neatly trimmed hair at the bottom.

Hua Cheng’s hips bucked again, making it twitch.

“Gege," Hua Cheng groaned, "you’re staring."

"San Lang, ah,” Xie Lian muttered hazily. ”You’re really... big."

The cock twitched again, this time spurring a few drops of precome from the head.

Xie Lian followed it with his gaze as it trickled down towards the balls.

“Mm," Hua Cheng hummed, "like what you see, gege?"

Xie Lian instantly nodded, suddenly desperate to get a hold of that magnificent cock.

"Can I touch it, San Lang?" he asked.

“Yes," Hua Cheng hissed through clenched teeth. ”You don’t have to ask, just do whatever you want."

Xie Lian reached towards it and grasped it softly with his right hand, giving it a slow stroke.

Hua Cheng moaned, and it immediately twitched in his hand.

"Yeah, just like that, gege,” Hua Cheng praised.

Xie Lian kept moving his hand, eyes focused on how reactive it was. For every slide of skin, it either leaked precome or jerked in his hand, helping Xie Lian easily get confident with his moves.

Another thing that also helped Xie Lian feel assured was how expressive Hua Cheng was. The usually so suave and relaxed man was constantly hissing and groaning on the couch, thighs shuddering and hips bucking.

It made Xie Lian feel really, really good.

Spurred on by the reactions he was reaping, he inclined his neck and licked away some precome from the head of the cock.

Hua Cheng moaned.

"That’s good,” he sighed heavily, "that’s so fucking good."

Xie Lian watched as Hua Cheng closed his eyes and rested his head against the back of the couch, before he slowly lapped at the dick again, prompting another whimper from Hua Cheng.

Never having tasted precome before, he found that he surprisingly liked it. It was salty and slightly bitter, but the texture was smooth and watery which made it easy to swallow.

"Ah, San Lang, you taste good,” he hummed, continuing tonguing at the head while working his fist over the rest of the length.

Hua Cheng lifted a hand to bite at its knuckles, his other hand shaped into a fist on the couch.

He didn’t answer, just made another deep grumble from deep within his chest, his visible eye pinned on Xie Lian’s mouth.

Xie Lian kept up the licking for a little while longer, alternating between lapping on the top or on the side. While he was busy tasting Hua Cheng, he kept pondering about the best approach to fit it inside his mouth.

His thoughts were interrupted, though, by Hua Cheng making the deepest groan he’d heard yet.

"‘m coming, gege,” Hua Cheng almost whined, "ah, gege, move quick–”

Xie Lian gasped, then closed his mouth around the head as Hua Cheng started coming. He had to move both hands to grasp his hips as they bucked violently, Hua Cheng almost roaring as he came, strong fingers grabbing Xie Lian’s hair to keep him still. 

There was so much come.

Xie Lian kept swallowing as the dick released burst after burst of come, some of it escaping out the side of his mouth. He maintained the stroking as well, helping Hua Cheng ride out his high.

The latter was panting hard, chest inflating for every breath, as he stared at Xie Lian licking up any stray drops.

“Gege," he groaned, "ah, your San Lang is sorry for– mhm, ruining your fun so quickly."

Xie Lian smiled at him.

"Not at all, San Lang,” he comforted, "this gege is only happy that San Lang enjoyed himself. Besides, we could always try once more when you’re hard again?"

Hua Cheng sighed, stroking Xie Lian’s cheek with a thumb.

"Of course, gege. I won’t need that long,” he murmured, "usually it doesn’t happen that fast."

Xie Lian merely continued smiling, happy with Hua Cheng caressing his face. He rested his chin on Hua Cheng’s knee as he let the man recuperate a little, his right hand still lightly playing with the now half-hard dick.

They sat in comfortable silence for a short while, Hua Cheng never letting go of Xie Lian’s cheek as his breathing slowed.

His cheeks were now full-on pink and slightly sweaty, his other hand pushing short, mussed hair away from his face, the movement impatient. His visible eye was closed, brows furrowed as he collected himself.

Xie Lian admired the other man for a bit longer, then registered that the cock in his hand was thickening again, stealing his attention.

“Ah," he said gleefully, then bent his head to gently lap at the side of the length.

Hua Cheng groaned, eye snapping open and hand palming Xie Lian’s cheek turning a little firmer. "Careful, gege, it’s sensitive."

“Mm," Xie Lian hummed as he slowly started working his fist over Hua Cheng again, sometimes cutting in to kiss the head.

The erection soon stood proudly once more, tip flushed slightly red.

Xie Lian wanted to taste it again.

Meeting Hua Cheng’s fierce gaze, he lowered his face and sucked the crown into his mouth.

A sharp inhale escaped Hua Cheng’s lungs as Xie Lian started bobbing his head, only taking in the first few inches. The girth was too thick for him to do anything but to take it slow, steadily getting to know the feel of it between his lips.

The tenseness of Hua Cheng’s thighs told him that the latter was doing his best not to rock his hips up, and he appreciated the man’s patience.

"Hah, gege,” Hua Cheng’s hand slid into his hair again, fingers curling to grasp the locks. ”You’re– ah – doing so well."

Xie Lian’s eyes flicked up to meet Hua Cheng’s gaze, watching his reaction as he tried to sink down a little further.

Again, the result was more than he could have asked for — Hua Cheng almost looked like he was in pain, face scrunching up but eye refusing to leave Xie Lian’s face.

“Mmh," he breathed out, "gege, that’s so hot."

Warmth heated Xie Lian’s cheeks and he moved his attention back to the erection, too embarrassed to hold eye contact.

This was his chance to experiment, after all, to see what giving a blowjob really was like. Everything he wished to try out, he could do with Hua Cheng.

Relaxing his jaw, Xie Lian let the dick slide out of his mouth, shining wisps of saliva and precome still connecting it to his lips. Before Hua Cheng could get the chance to question what he was doing, Xie Lian ducked to let his tongue follow the thick vein on the underside, slowly licking from the bottom to the top and back down again.

It was an intriguing feeling to be so close to Hua Cheng, and in such a different way than he was used to. To feel the man on his lips, the weight of him on his tongue.  

It was a foreign and strange experience, but somehow, having Hua Cheng there with him made him feel safe and relaxed.

"San Lang,” Xie Lian murmured against his shaft, "how I can make you feel good?"

Hua Cheng’s grip in his hair tightened a little.

"You’re already doing amazing, gege,” he groaned, "almost a little too well."

Xie Lian lapped up the leaking precome, before he continued.

"But I want to know what feels the best. Is it when I do this–“ he licked the head once more, prompting another gasp from Hua Cheng, "or when I take it inside my mouth?"

"Gege."

"San Lang, ah,” Xie Lian started stroking with his right hand again, "please teach your gege."

The man in question inhaled deeply once more, then nodded and moved his hand back to Xie Lian’s jaw.

"Let me show you, gege,” he breathed, "just open your mouth for me – yes, like that."

Xie Lian obediently gaped as Hua Cheng gently led his dick back into his mouth, before pulling Xie Lian slightly closer towards him so the latter swallowed more of it.

"Very good, gege,” Hua Cheng praised. “Now, just keep sucking as I– ah, yeah, just like that–“

Xie Lian dutifully kept sinking down the length, taking in more and more until the tip hit the back of his mouth, making him cough.

Hua Cheng pulled at his chin to lift him up again but Xie Lian persevered, holding still as he blinked stray tears from his eyes. He then turned his gaze to Hua Cheng as he started bobbing his head up and down, letting the dick graze his throat every time he sunk.

The sight of Xie Lian’s glistening eyes and stretched, red mouth around his dick made Hua Cheng gasp and buck up once more, sliding even further down Xie Lian’s mouth.

"Gege, please slow down,” he bit out through a clenched jaw, "otherwise, I’m gonna– gege!"

Xie Lian had moved his arms to rest on Hua Cheng’s thighs as he shifted closer, looking at the man with half-lidded eyes as he worked his dick even faster. He used his right hand to service the part he couldn’t fit between his lips, and lazily used his left hand to fondle Hua Cheng’s balls. The latter’s hand on Xie Lian’s jaw turned iron stiff, thumb gliding over to touch the side of Xie Lian’s mouth — feeling how stretched it was from swallowing Hua Cheng.

Salty precome kept coating Xie Lian’s tongue, the amount turning more generous as Hua Cheng kept moaning, hissing, and unintentionally roll his hips.

“I'm close again, gege,” Hua Cheng gasped, "don’t wanna come yet – please – Xie Lian, ah–“

The man in question opened his eyes wide again at the mention of his actual name, taking in Hua Cheng’s unhinged state — mouth hanging open, brows scrunched tightly, fingers clawing at the couch.

Xie Lian hummed happily and squinted up at the other, pleased with seeing this side of his friend, blood thrumming with glee and arousal. As he kept working and sucking on Hua Cheng’s cock, he moved his left hand down to palm his own bulge, moaning as it finally got some stimuli. Pressing down on his own length, he sped up the fist he had around Hua Cheng and lifted his head to rest his tongue behind the tip, lapping and pressing kisses to it.

“Uhng," Hua Cheng’s hips were lifting sporadically as his orgasm approached, “ge–"

Warm, thick drops of come hit Xie Lian’s face as Hua Cheng finally lost his composure, and he jolted as his own cock released at the same time, wet bursts soaking his pants.

Gege–" Hua Cheng groaned as he kept coming, Xie Lian hurriedly swallowing as his mouth filled up whilst he kept milking Hua Cheng’s dick.

“Mm," Xie Lian sighed, his own shudders stilling as he came down from his high, busy with prolonging Hua Cheng’s.

A few long minutes later, Hua Cheng’s climax had cooled down. Xie Lian let go of his length to thumb the drops that had landed on his face into his mouth.

Hua Cheng groaned.

"That was incredibly good, gege,” he said. "You’re, ah, a natural."

XIe Lian blinked at him, then smiled. "Why, thank you San Lang."

Hua Cheng kept panting lightly as he pushed himself back into his boxers, then stilled.

"But gege!" he exclaimed abruptly, “you– you!"

He looked devastated as he bent down to pull Xie Lian up onto his lap, strong hands gripping him. He rested his hands on Xie Lian’s waist as he made sure the man sat comfortably.

"Please forgive this horrible San Lang, gege,” Hua Cheng shot him a genuinely distressed glance, "for only thinking about his own pleasure and not yours. Please allow me to make you feel good as well?"

Xie Lian kept the smile on his lips and patted Hua Cheng’s shoulder with his left hand.

"No need, San Lang. This gege is doing great."

"I’m afraid I’ll have to insist, gege,” Hua Cheng looked tormented, "won’t you humour me?"

Xie Lian sighed lightly.

"I’m sorry, San Lang, but I don’t think I can recuperate as quickly as you. Otherwise, of course I would let you help me."

“Recu–" Hua Cheng frowned. “What–?”

His eye darted down to Xie Lian’s lap, then widened as it saw the liquid staining the thigh next to his crotch.

Xie Lian blushed and sheepishly rubbed his chin.

"Gege?"

Xie Lian coughed. Hua Cheng’s face changed from looking astonished to looking thrilled.

"Gege enjoyed pleasuring his San Lang so much that he came?" he eagerly inquired.

The older man looked away, face turning bright red.

Hua Cheng grinned, then moved his mouth towards Xie Lian’s ear.

"Gege promises that he’ll let San Lang help him next time?" he was almost purring.

Peeking shyly at his friend, Xie Lian couldn’t help but to nod.

Notes:

Yes, this fic was written to support my agenda that Hua Cheng definitely came immediately during their first sexual interaction. Being so in love with his gege, it’s only natural that a simple, intimate touch from the man could make him burst! Also, Hua Cheng said gege 49 and a half times in this fic. That’s… a lot.

Anyway, this is my first Hualian fic, so I hope you enjoyed! 💛 I’m sure there’ll be many more to come! I already have a few ideas for a follow-up to this story, so let me know if that’s something you wish to see!

If you wish to, you can follow me on twitter here, and you can find the promotweet here 💛☀️
